Silicone Hermaturia Catheter: A Core Diagnostic and Therapeutic Instrument in Clinical Urology
As a specialized foley catheter widely used in urology, Silicone Hermaturia Catheter features an inflatable (air/fluid) balloon with larger volume at its tip. Boasting “stable fixation, tight sealing and versatile functions”, it serves as a core integrated instrument for treatment and nursing in key scenarios like post-operative drainage, hemostasis and bladder distension.
Core Structure and Design Features
Optimized based on traditional catheters, it mainly comprises catheter body, large-volume balloon, drainage lumen, inflation/infusion lumen and one-way valve. Key design features:
Catheter Body: Made of medical silicone or latex with good softness and biocompatibility, minimizing urethral mucosa irritation and suitable for long-term indwelling.
Large-Volume Balloon: It fits closely with bladder inner wall after inflation/infusion for reliable sealing.
Core Clinical Application Scenarios
1. Indwelling After Benign Prostatic Hyperplasia (BPH) Surgery
Smooth end forms sphere/oval after inflation, avoiding bladder mucosa injury and preventing urine leakage or irrigation fluid reflux.It’s the primary choice after BPH surgeries (e.g., TURP, laser resection). Inflating the balloon (15-30ml normal saline/sterile water) compresses prostatic fossa wound to reduce bleeding, while its tight fit with bladder neck prevents urine reflux. Usually indwelled 3-7 days until edema and bleeding subside.
2. Compression Hemostasis for Bladder Hemorrhage
For moderate-severe bladder hemorrhage (caused by trauma, tumor, inflammation, etc.), the inflated balloon provides uniform compression to stop bleeding, while the drainage lumen removes blood-stained urine, avoiding clot-induced urethral obstruction and buying time for further treatment.
3. Adjuvant Therapy for Bladder Distension
Applied in bladder distension therapy for overactive bladder, interstitial cystitis or small bladder capacity. Sterile saline injected via catheter expands bladder cavity with the balloon’s support, restoring bladder volume and contractile function. Pressure adjustment via balloon ensures safety and comfort.
Clinical Advantages and Precautions
Effective Hemostasis: Direct physical compression on bleeding wounds, faster than drug hemostasis, suitable for post-op scenarios.
Stable Fixation: Large contact area enhances anti-displacement ability, reducing catheter detachment risk during patient activities.
Superior Sealing: Tightly blocks bladder neck to prevent urine leakage, keeping perineum dry and lowering infection risk.
